What I've read is that inflation in Germany in the 1930s was actually very usefull. They had an enormous amount of debt they were incapable of servicing. The huge inflation cut the debt to pieces very efficiently. The inflation was not the cause of German problems, it was a symptom of problem of having a too large debt. It is sort of like blaming the flu on the fever. The fever might feel bad but it is actually your body's way of fighting the flu.
Probably you should read another version of how inflation "helped" Germany. When you have hyper inflation like that it may be good for paying back your debts, but your creditors soon realize that their payments are worth nothing (because you just print paper, you don't create value like that), and you disintegrate all private investment in your country. Why do you think the Third Reich nationalized every industry out there?
My understanding is that German debt was not denominated in paper, but that they had to print money to buy gold at whatever rapidly falling rate people would give. Presuming my understanding is correct, the debt was certainly the root problem, but the inflation wasn't helping - it made it harder to buy the next payment's gold.
